What is the pH value of QIAGEN's Nuclease-Free Water?

At 22°C, Nuclease-Free Water has a pH value of between 5.0 and 6.5. It is not possible to determine the pH of highly pure water exactly. Therefore, many publications/industry standards do not provide a pH specification for highly pure water. Highly pure water does not contain enough ions or impurities for an exact pH determination. In general, values between pH 5 and 8 are obtained.
